[PATCH] Add a few might_sleep() checks
Add a whole bunch more might_sleep() checks. We also enable might_sleep()
checking in copy_*_user(). This was non-trivial because of the "copy_*_user()
in atomic regions" trick would generate false positives. Fix that up by
adding a new __copy_*_user_inatomic(), which avoids the might_sleep() check.
Only i386 is supported in this patch.
